How to Prevent xmlns from Appearing When Appending in Data Stitch Action (OIC)

Hi everyone,

I'm working in Oracle Integration Cloud (OIC) and using the Data Stitch action to append XML elements to a variable. The issue I'm facing is that when I append a node-set, the resulting XML includes an unwanted xmlns="..." (namespace declaration) on the appended elements.

Here’s the context:

• Both the Data Stitch variable and the node-set being appended have the exact same structure.
• However, they originate from different sources — one from a REST response and the other one from file stage.
• Even though the structures match, the appended elements still carry a namespace declaration that I want to avoid.
